Recently, the winning bid results of the investment bidding project for the Mengyin Pizhou Expressway were officially announced, marking an important step in the construction process of this expressway project with a total investment of over 10 billion yuan.

Detailed planning of high-speed routes

The starting point of the Mengyin Pizhou Expressway is located in the southeast direction of Mengyin County, at the southern hub of Mengyin where the Beijing Shanghai Expressway intersects with the planned Weizhou Expressway. This route will utilize the Weizhou Expressway and Bintai Expressway to extend to the Bintai Expressway in the west of Tongshi Town, Pingyi County, and set up a Tongshi hub; Subsequently, a new section of road will be built in the southeast direction, passing through the west of Pingyi County's local town and the west of Zhutian Town in Fei County. It will connect with the Linteng Expressway to the northwest of Xujiaya Reservoir, continue southwest of Xinzhuang Town in Jinzi County, and connect with the Lanhe Expressway to the south of Shangyan Town. After reaching the northeast of Nanqiao Town in Lanling County, it will connect with the proposed Linxu Expressway and establish the Lanling South Hub. Finally, the Linxu Expressway will be used to extend southward to the border of Lushu Province in Changcheng Town, Lanling County, and connect to the planned expressway in Jiangsu Province.
